Frizz isn't just part of having curly hair. More often than not, it's caused by dryness, which lifts the hair cuticle and allows moisture in, creating that fluffy, frazzled look.

One of the biggest culprits is humidity. Here in the UK, our damp climate and near-constant drizzle make frizz a year-round battle, so it's safe to say I've put plenty of the best anti-frizz products to the test.

Beyond the weather, some everyday habits can also be making frizz worse. Hot showers can strip away the hair's natural oils, while over-brushing can leave curls looking fluffy and undefined. That's why common frizz-fighting advice includes finishing with a blast of cold water, only brushing hair when it's soaking wet, and switching to sulphate-free shampoos.

Thankfully, there’s no shortage of products promising to fight frizz. After testing countless formulas (and ruling out plenty along the way), I’ve found the ones that truly deliver for frizz-prone curls.

A cult favourite in the curly community, this silicone-free styling jelly promises 'long-lasting, frizz-free definition' via a medium-hold cast that you scrunch out once dry. My repurchase rate for this gel must be pushing 50, making it the most consistently used item in my haircare routine.

It works best on wet or damp hair, scrunched and left to set for a few minutes. The formula isn't sticky yet provides decent hold and creates shiny, silky, frizz-free curls and waves once scrunched. The gel is also brilliant for touch-ups and non-wash-day hair, taming flyaways and forming defined curls. My one wish is that the packaging was in tub rather than tube form as it's tricky to scoop out the last of the gel when you're reaching the end of your bottle.

A glossy all-rounder, Ouai’s hair oil is a silicone-led, lightweight styling oil promising to smooth frizz, seal split ends and deliver heat protection in one pump. In practice, a single pump (two for thicker hair) is enough to tame flyaways and add definition without tipping into greasiness, leaving lengths soft, swishy and convincingly 'done'.

The brand’s high-gloss claims largely hold, though the shine owes more to coating than care, making this more of a finishing oil than something for overnight hydration treatment. Results last a full day on styled hair and its floral, slightly heady scent (violet, gardenia) lingers. The drawback? Easy to overapply, which considering the price point, means you can run out of this dinky bottle faster than you'd like.

Another long-time staple in my hair routine, this OGX formula does rely on silicones and coconut oil, which some certified 'curly girls' might have issues with. However, this conditioner delivers instant smoothness and slip, doing a decent job of reducing surface frizz and adding shine, particularly on wavy or loosely curly hair, and leaves strands feeling soft and more manageable.

OGX claims this conditioner is 'pH balanced,' restoring your hair to its natural acidity, resulting in less frizz. I can't confirm that it's the work of this newly upgraded formula, but I can say that my curls are buttery soft. Compared with other leading conditioners from curl specialists at a much higher price point, this bargain choice continues to impress.

  • Take note- Could be too heavy for fine hair

This dense cream sits somewhere between a leave-in conditioner and a styling product, using shea butter and coconut oil to smooth the cuticle and reduce frizz. When smoothed and scrunched into wet curls, it delivers on softness and shine, particularly on dry hair, and can noticeably tame fluffiness without adding extra weight.

That said, if your hair is finer in texture, the heavy, oil-rich formula can seal rather than hydrate, leading to build-up. You’ll also need to be careful not to overapply, as this can leave finer curls greasy, limp and weighed down. However, the definition and frizz-fighting qualities made this cream a winner over other brands I tested.

  • Smooths frizz without adding weight

  • Take note- More subtle results for thicker textures

Davines’s curl building serum is a leave-in styler built around conditioning agents and 'elastic' film-formers that promise definition, bounce and humidity resistance. On wet or damp hair, a 5p-sized amount distributes easily, smoothing frizz and taming flyaways while encouraging soft, touchable definition rather than a rigid cast. The brand’s claims largely hold: curls look glossier, more uniform and remain manageable through the day, though longevity dips in high humidity.

Crucially, it avoids crunch, but that also means lighter hold on looser waves. Used in combination with a gel, this serum is even more effective. The fresh, slightly spicy-woody scent lingers pleasantly, but the product’s subtle results mean the anti-frizz properties may be underwhelming for thicker textures without layering, making it relatively pricey for the results.

  • Take note- The banana scent isn’t to everyone’s taste

This purse-friendly, multi-tasking mask doubles as a conditioner and leave-in, using banana extract and shea butter to coat strands and smooth the cuticle for a softer, less frizzy finish. It does deliver instant slip and shine, particularly on dry or textured hair, and the silicone-free formula avoids that overly coated feel. The formula is thick and easy to apply in the shower and feels more luxe than the affordable price tag suggests it would.

The banana scent is reminiscent of tuck-shop foam bananas, which, while I enjoy, is not to everyone's taste. Plus, if used as a leave-in, this can sit heavily, leaving my hair a little waxy, so I prefer to stick to using it as a mask once a week.

  • Take note- The bristles are a little stiff

Designed specifically for curls, this wet-use brush uses flexible, two-tiered teeth to glide through knots while smoothing the cuticle - an approach that does help minimise frizz during detangling rather than aggravating it.

During testing (I also did a test on dry hair for completeness – a cardinal sin for anyone with curly hair), I did notice a reduction in post-wash fluffiness. The plastic design also makes this brush easy to keep clean – something to keep in mind if you regularly use leave-ins that can build up on brushes. Sensitive scalps watch out – the firm teeth can feel harsh.

  • Not a catch-all for curly hair woe

Less a styling product and more a preventative step, this satin pillowcase is designed to tackle frizz at its source: overnight friction. Unlike cotton, which can rough up the cuticle and absorb moisture, the smooth satin surface allows curls to glide, helping reduce tangles, breakage and that tell-tale morning halo of frizz . In practice, it does make a noticeable difference to next-day smoothness, particularly for looser curl types or anyone prone to dryness.

However, the 'wake up to perfect curls' promise is optimistic. While it minimises additional frizz, it won’t preserve definition entirely - especially if you move around in your sleep. You'll still need some styling product application in the morning.

  • Soft yet effective hold on curls

  • Take note- The strong hold might be too much for finer hair

Hairspray can be a menace for frizz-prone hair, especially when dealing with the sticky, wonky-curled fallout the next day. Curlsmith’s flawless finish is a fine mist, alcohol-free styler promising strong hold without crunch - a claim that, largely, stands up. Powered by flexible polymers, it sets curls and smooths frizz while keeping definition intact and surprisingly touchable. A light, even mist (held at arm’s length) is enough – overapply and you risk stiffness.

Tested on dry, styled or even very-so-slightly-damp hair, curls stay soft, not shellacked, with a clean, slightly sweet scent that lingers. The trade-off? On finer hair, the touted strong hold can feel heavy, dulling natural movement.

  • Take note- Not super hydrating

A budget-friendly cleanser aimed at waves and looser curls, Cantu’s weightless smoothing shampoo leans on humectant-rich blue agave and lightweight oils to promise frizz control without heaviness. It lathers easily (thanks to stronger surfactants than some 'gentle' rivals), lifting build-up while smoothing the cuticle - flyaways are softened, but true definition relies on follow-up styling.

A 50p-sized amount was enough for my below-shoulder-length hair during testing, though thicker hair may need more. Results feel clean and lightly conditioned and the sweet, fresh scent is pleasant but fleeting. It's not as nourishing as some other leading brands tested, but when followed up with hydration-focused styling products the weightless finish is worth it.

  • Can cause knottiness if used too often

Positioned as a day-two curl refresher, this fine mist uses a blend of oils, butters and light conditioning agents to rehydrate hair and smooth the cuticle, helping to soften frizz without fully restyling. Post-wash day, my curls flatten and become thick and unmanageable, so I'm always on the lookout for day-two products to help redefine and fight frizz.

This spray is easy to apply and doesn't spritz out too much product at once, meaning it can be applied directly to your hair. However, restraint is key here as a heavy application can result in tacky curls and build-up, leaving hair coated and knotty rather than genuinely refreshed. It’s also at a pretty high price point for a nice-to-have.

If I’m going to spend time diffusing my curls, it’s got to be worth it. The Bellisima Italia diffon supreme has been my hair dryer of choice for the past couple of years, with a comfortable and lightweight design and a choice of three temperature levels. They all felt gentle and comfortable while drying a full head of curls in around 10 to 15 minutes.

The extra-large size can be unwieldy to store and travel with, but it makes light work of my medium-length hair. The lack of curl crunchiness impressed me, too – likely down to the argan oil technology. The cool air shot also provides a much-needed curl lock-in that results in the bounciest curls I’ve had outside of the salon.

  • Take note- The ‘weightlessness’ might not provide enough hold for thicker textures

There’s something quietly reassuring about a mousse that doesn’t promise miracle curls but instead leans into the basics – and this one is exactly that. Designed as a lightweight styler, it aims to boost volume, define curls and tame frizz using a protein-rich blend of rice water and pro-vitamin B5 . On paper, it’s a dream for fine or easily weighed-down hair. In practice, it delivers impressively soft, bouncy curls with minimal crunch.

Frizz is smoothed rather than eliminated, which feels honest: expect polish, not perfection. Longevity is decent for a mousse – a full day of hold, but second-day curls need reviving. The 'weightless hold' claim mostly checks out, though that lightness is also its downfall. Thicker hair types may find the hold too gentle, especially in humidity. Still, for airy volume and touchable definition, it’s an easy, everyday win.
